Some olive oils break down faster when heated, making them less healthy. This study tested six kinds by cooking them hot and checking what changed.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Heating olive oil really hot makes it get gunkier — about 4.5 times more than at a lower heat — but even at the highest temperature, it doesn’t get gunky enough to be considered unsafe by food safety standards.
Some olive oils, like Picual and Cornicabra, handle high heat better than others—they keep more of their good stuff and make less gunk when cooked.
When you heat olive oil super hot, it starts forming gunk (polar compounds), but even at the highest temperature tested, it didn’t get bad enough to be considered unsafe for frying by food safety rules.
When subjected to prolonged heating, extra virgin olive oil generates significantly higher levels of polar compounds and lipid oxidation byproducts than coconut oil and ghee.
Olive oil, due to its 11% polyunsaturated fatty acid content, exhibits greater oxidative degradation under heat compared to animal fats with <5% polyunsaturated fat content.
